Boox M92 with defective pixels
Hello,
I mentioned that my M92 has an strange Pixel Error: The same picture but with inverted colors This 3 grey Pixels accur only when some surrounding pixels are black and some others white. Normaly I can't see this error but sometimes small letters gets defaced a little bit. Does an E Ink display has Pixel Fault Classes like an LCD? Can I replace the device? I bought it from Booxtor. Thanks |

You'd have to ask Booxtor. Looks certainly defective to me, they don't change their state.
Question - is this a simple checkboard pattern with pixels? Looks like a good idea to use when checking the device in a store. |

That kind of customer service gets my vote. My DR800S's screen died completely a few days ago and I was looking for a replacement.
Hope you ordered a lot of them :) |

I have the same problem (also bought from booxtor); I wonder how frequent it is.
Here are pictures of my dead pixel (the first is a bit off focus; the checkerboard is 2x2 pixels, so the dead spot is rather large) Last edited by psv; 01-06-2012 at 03:26 PM. |

That would be horrible, it would be ridiculous to fix one problem and create another...

That was a whole different problem, with the digitizer, not the screen itself.

eink is not effected by magnetic fields from simple speaker magnets. it would take a much more powerful magnetic field to interrupt the refresh of the pixels

It's still suspiciously close to the speaker on the backside.
@medvedev: Can you please post an image like psv from your whole display? |
